Maggie - just keep those positive feelings/vibes/sense of humor coming - you just never know!
Many years ago my younger sister was diagnosed with a brain tumor - they basically gave her 6 months - she managed 4 years - and they were difficult sometimes, but for the most part they were wonderful years with her - not to hijack your issue in any way - but you just never know. I think it is so wonderful that your husband has hope - every single day is precious, and again, just remember there are many, many, many, of us out there for you both -- aahhh you've already seen that. Its amazing isn't it? Been there, done that, been amazed at the support here, been the recipent of that - its your time now, and we are all there for you, whenever, whatever you need - we are there for you!!
Love and thoughts and prayers for you both every single day!
